TE Connectivity 640604-7 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640604-7 is a 7-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete product status.

Due to its obsolete classification, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production, repair, and maintenance applications. The substitute part identified maintains functional compatibility while offering improved product status and compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640604-7 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-640604-7 qualifies as a direct equivalent because it maintains identical specifications in the following key parameters:

• Connector type (Receptacle)
• Number of positions (7)
• Pitch (0.156" / 3.96mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (18 AWG)
• Wire type (Discrete or Ribbon Cable)
• Mounting type (Free Hanging In-Line)
• Feed through feature
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Orange)
• Series designation (MTA-156)

The primary difference between the main part and substitute is the contact finish composition and product status, with the substitute offering tin finish instead of tin-lead and active product status instead of obsolete classification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-640604-7 is the appropriate selection for new designs and ongoing production applications. This recommendation is based on the following factors:

Product Status: The substitute part carries active product status, ensuring continued availability and manufacturer support. The main part 640604-7 is classified as obsolete, which restricts future procurement and technical support.

Regulatory Compliance: The substitute part 3-640604-7 is RoHS compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The main part is RoHS non-compliant and does not meet these standards.

Contact Finish: The substitute part features tin contact finish instead of tin-lead. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and electrical performance characteristics. The tin finish aligns with RoHS compliance requirements.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute, ensuring direct compatibility in existing circuit designs and connector mating applications.

For applications where the main part 640604-7 is currently in use, transition to part 3-640604-7 is supported by complete parameter equivalence and does not require design modification.

Frequently Asked Questions (FAQ)

Q: Can the 3-640604-7 substitute directly replace the 640604-7 in existing designs?

A: Yes. The 3-640604-7 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, and mounting configuration. Direct substitution is supported without design modification.

Q: What is the difference between tin-lead and tin contact finishes in this connector?

A: Both finishes are applied at identical thickness (80.0µin / 2.03µm). The tin finish in the substitute part meets RoHS compliance requirements, while the tin-lead finish in the main part does not. Electrical performance and contact resistance characteristics remain equivalent.

Q: Why is the main part 640604-7 classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production and support for this part. The substitute part 3-640604-7 is the active equivalent and is the recommended selection for all new and ongoing applications.

Q: Are there packaging differences between these parts?

A: The main part 640604-7 packaging is not specified in available documentation. The substitute part 3-640604-7 is supplied in bulk packaging. Both parts are available in new original condition.

Q: Does the MSL rating differ between these parts?

A: No. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts subject to the same export classifications?

A: Yes. Both parts carry ECCN classification EAR99 and HTSUS code 8536.69.8000, indicating identical export control and tariff classifications.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the main part and substitute support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 18 AWG wire gauge.
